My history project is on the Chicago Cubs and Chicago White Sox rivalry and history for the city of Chicago.
The first site gives information on the history of the ballclub, Wrigley Field and has a nice timeline for the students to review.
www.chicago.cubs.mlb.com/chc/history/index-

The next two sites are encyclopedia and reference internet sites that has information from 1876- Present.
www.sportsencyclopedia.com

The next site is:
www.baseball-reference.com/teams/chicagocubs

The Chicagp White Sox sites are the same:
www.chicago.whitesox.mlb.com
www.sportsencyclopedia.com/al/chisox.com
www.baseball-reference.com/teams/CHW/


The students will be able to gather a lot of information on both teams and their history through these sites.
